Application December 2, 1933, Serial No. 700,744

1 Claim.

This nivention relates to an attachment for use in connection with internal combustion engines whereby combustible fumes can be collected from crank case of the engine, cleaned, mixed with 5 a percentage of lubricating oil, and then delivered to the intake man fold at a point between the carburetor and the intake of the engine.

It is a further object of the invention to provide a simple, compact and emcient device which can be applied readily to an engine structure.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of con struction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing:

Figure l. is a side elevation of a portion of an internal combustion engine having the present improvements combined therewith.

Figure 2 is an enlarged section through the oil container forming a part of the attachment.

Figure 3 is an elevation of a portion of the breather of the crank case, a portion being broken away to show its connection with the attachment.

Referring to the figures by characters of reference E designates a portion of an internal combustion engine provided with the usual intake manifold M to which fuel is supplied from a carburetor C. The breather of the crank case has been indicated at B and is of the usual construction.

The present invention includes a bracket I which is detachably engaged by the threaded upper end of a container 2 which can be formed of glass and is adapted to hold lubricating oil as shown at O. Secured in this bracket so as to open downwardly into the container 2 is a tube 3 the lower end of which is located close to the bottom of the container while its upper end is con nected by a tube 4 to a nipple 5 opening through the wall of the breather B.

Another tube 5 opens through the bracket l into the top portion of container 2 and communicates with the intake manifold M as shown at I, this point of communication being located between the carburetor C and the intake of the engine.

In the operation of an internal combustion engine a certain percentage of gas escapes past the pistons into the crank case. The present in vention provides a means whereby the fumes thus contained in the case are withdrawn, purified or refined and, after being supplied with a small percentage of lubricating oil are delivered into the engine where they serve not only to provide power but also to lubricate the combustion chambers of the engine. The suction set up through the operation of the engine exerts a pull through tube 5 so that fumes which have accumulated within the crank case will be drawn from the breather B through tubes 4 and 3 and be delivered into container 2 close to its bottom. They will then flow upwardly through the body of oil 0 which thus acts not only to cleanse or purify the fumes, removing from them any solids mixed therewith, but also to mix a small percentage of lubricating oil with the gas thus purified so that this oil will be carried in suspension with the gas through tube 6 to the intakes of the engine.

Obviously the container 2 can be removed readily for the purpose of filling or cleaning it and the entire attachment can be applied easily to an engine.

It is preferred to place a small port 9 in the tube 3 at a point within but close to the top of the container 2. Thus hot fumes entering the tube 3 from the breather will have a portion thereof escape into the space above the level of the oil where these hot fumes will mix with the oil fumes caused by the upward flow of air through the oil. Consequently the temperature of these oil fumes will be raised materially before the fumes escape into the pipe 6. An air inlet valve 8 is also provided preferably within the top of the container. Thus by opening the valve a desired amount of air can be admitted to the container for the purpose of regulating the amount of suction through the tube 4. With this arrangement the oil in the container 2 will not be used as rapidly as would be the case should all of the suction be carried on through the tubes 3 and 4.

While the device is especially useful as a gas saver, it is also equally advantageous because of its efficiency as an oiler or lubricator for the engine valves and the tops of the cylinders.

While the improvements are designed especially for use in connection with the engines of automobiles, they can, obviously, be used with all types of internal combustion engines wherein there is a crank case to which gases will escape during the operation of the engine.

What is claimed is:

The combination with the intake manifold and the crank case breather of an internal combustion engine, of a bracket, a container detachably engaging at its upper end with the bracket and extended therefrom, said bracket constituting a closure for the top of the container, an outlet tube opening through the bracket into the top portion of the container at one end and opening at its other end into the intake manifold, an intake tube secured in the bracket and extending downwardly within the container, a connection between the intake tube and the breather, said
